Subject: 29.2; Proced auto update should only update visible buffers
Date: Wed, 13 Mar 2024 22:00:17 +0100
Dear Emacs developers,

I use proced with 'proced-auto-update-flag' set to 't'. Often I quit the
window showing proced buffer and later some profile shows that the timer
used to update proced is taking a big chunk of time.

Since updating the proced buffer is a somewhat expensive operation, I
think the update should happen only if a proced buffer is visible.

I can send a patch to that changes 'proced-auto-update-timer' to this
effect.

Thanks,
Rahguzar

As a user option, this sounds useful.  So please do send a patch, but
please add such an option, because I can imagine users who'd like
Proced buffers to be always up-to-date, regardless of whether they are
displayed.

Thanks.

What about a special value 'visible' for proced-auto-update-flag instead
of a separate option?

The only wrinkle might be how to set this value using
proced-toggle-auto-update. There is also the slight inconsistency that
it makes proced-auto-update-flag not a flag.

Yes, a good idea.

Make it cycle through the values?

Not a catastrophe, IMO.
